The Component Tower is about as simple as defensive structures come when first built; a heavy brick base, a couple of power linkages, and nothing on top.
The Component Tower is designed to streamline the defense of Russian bases by serving as a cheap and quick modular base for further upgrades, and can fit three separate defensive systems to this end.
The Component Tower has no real use on its own, but can be upgraded with one of three possible modules to make it an effective defense: RPG Launcher, Arena System and Tesla Coil.
Behind the scenes
- Prior to 1.85 the Component Tower has the Air Raid System upgrade which worked similarly to the current Early Warning Outpost that replaces it.
